Facebook introduced hashtags (#) in June 2013 to organize the 4.75 billion pieces of content shared on Facebook daily and surface conversations in Graph Search. Hashtags allow indexing of posts and discovery of brand, product, and location discussions. Marketers can now coordinate campaigns, track trends in real-time conversations, and join discussions at a scale not previously possible. In the future, Facebook may support hashtag targeting, promotion, and analytics to further help marketers understand and drive business objectives through social media conversations.
